2. Depressingly, I fold the turn. It's either that or felting one pair against someone showing classic signs of strength and without a read I can't let myself do that.

3. Yes, fold flop. Instinctively I like your turn bet, but in reflection, if he's got a good enough hand to raise the flop (and it's a proper raise, note, and he's in the BB so his hand could literally be anything), then I'm not sure he's folding on a board with only one completed draw and few obvious monster holdings - could you realistically have anything better than KT, A8 in your hand? I'm pretty sure JQ doesn't push in your spot.
